PRIMULA CONFERENCE. 



125 



glossy, glaucescent, stiffish, oval leaves, almost entire, or toothed, 

 a little scape, a purplish calyx (a frequent inheritance from Wulfeniana t 

 to which the whole form more nearly approaches), and two or three 

 large lilac -rosy flowers. 



And, finally, I would urge that much more attention be paid by 

 gardeners, cultivators, and catalogues to these Natural Crosses of 

 Primula, which, as a whole, are quite as brilliant a race as their parents, 

 but at present languish too deep in undeserved obscurity, hidden 

 from us in lists by false, doubtful, or conflicting names. Indeed, 

 there are certain hybrids, such as Kellereri, Forsteri, pubescens, Heeri, 

 and the magnificent intermedia, that I should be inclined to rank for 

 show, ease of culture, and general garden value far above any of the 

 species, except spectabilis, Clusiana, marginaia, carniolica, pedemon- 

 tana, hirsuta, and Auricula, greatly exceeding several even of these, 

 as they do, in heartiness of habit, freedom of flower, and general 

 amenability to any reasonably careful conditions of culture. And it 

 will yet be possible for us to add still more to our treasures, by working 

 farther for ourselves along the lines of nature, with as much skill and 

 success, I hope, as that which has already produced us Primula X 

 ' Marven.' 



Table of European Primula Crosses. 



Subsection Eu-Auricula x Subsection Brevibracteatae (P. marginaia, 

 P. viscosa, P. carniolica). 



P. Auricula X P. carniolica = P. x venusta. 



(P. x venusta x P. marginaia = P. x 1 Marven,' garden cross.) 



Subsection Eu-Auricula x Subsection Rhopsidion (P. Kitaibeliana, 

 P integrijolia, P. Allioni, P. tyrolensis) . 



P. Auricula x P. tyrolensis = P. x obovata, Huter (extremely 



doubtful). 



P. Auricula x P. integrijolia = P. x Escheri, Briigger. 



Subsection Eu-Auricula x Subsection Erythrodosum (P. villosa, 

 P. hirsuta, P. oenensis, P. apennina, P. pedemontana, P. cottia). 



P. Auricula x P. oenensis —P. X discolor, Leybold (Portae, 



Huter). 



P. Auricula X P. pedemontana = P. X Sendtneri, Kellerer (obscure 



garden cross) . 



P. Auricula x P. hirsuta = P. x pubescens, Jacq. (P. X helveticai 



Don ; X rhaetica, Gaud.; x alba, 

 Hoffmsg. ; X alpina, Schleicher j 

 X intermedia, Van Houtte ; x 

 Goblii, Kerner ; x Arctotis, Ker- 

 ner ; X Kerneri, Gobi and Stein ; 

 X Peyritschii, Stein). Infinitely 

 variable and fertile.
